“DOORS OPEN MILWAUKEE will open 100 downtown sites for you to explore, some will have guides and some you will be free to explore on your own.
September 24th & 25th, 2011, you will have the opportunity to see some wonderful buildings free-of-charge to the public –buildings that hold hidden treasures and special stories – from churches to office buildings, theaters to work sites, museums to hotels, clubs to universities; all sites of historic, architectural, cultural, or commercial interest. It’s like getting a free backstage pass to areas you seldom see – from U.S. Bank’s 41st floor observation deck to Bradley Center locker rooms, from behind the curtains at the Pabst Theater to an up-close look at the Jones Island Water Reclamation Facility to see how Milorganite is made. ” -from doorsopenmilwaukee.org
No one could see all there is to see in one weekend, but fear not, they are hoping to make this an annual event.
